. Application filed .Tune 2,3,

has the combined function of serving as: aY

mixing chamber for the fuel V and air, and the walls of which contain passages which are heated byy the flame from the burner oriice so as to vaporize saidfuel ready'for combustion.

Y rPhe object of my invention is to provide a vaporizing nozzle of simple and 'sturdy/con? struction adapted to be. us-ed with fuel such u as kerosene and other hydro-carbons requiring vvheat for vaporization.

Ak further object of myinvention is to provide a vaporizing nozzle with a plurality of longitudinal passageways formed inthe walls thereof, lsaid passageways being `all .connected in series so as'to form one continuous passageway through which the fuel is required to pass and which, when heated by the flame extending from'l the vburner orifice, will be vaporized completely so that no liquid fuel will. be delivered to the. orifice.

yVarious experiments and tests in' con- :nection with., vaporizing nozzles have re- -vealed that in yorder to obtain perf-ect` combustion of the fuel the same must be obstruct ed in its passage therethroughand in my Vimproved device I have provided transverse ribswhich, besides-providing communication betweenthelongitudinal passages,act as an obstruction to theffuel and whenfthe same is directed against the same from the burner orifice, there .is a .tendency for the fuel Vto rebound and break up, becoming thereby better mixedjwith air, and capable Ofbeingl entirely consumed which is not the case' where the fuel is free to pass entirely through the nozzle without obstruction.

Many other advantages and vobjects of my invention will be apparent when considered in connection with the following description, reference being'had to the accompanying drawings, in which: i

Referring more particularly to the drawing,y Grepresentsl my improved vaporizing 7,65 Y

nozzle which has the combined uses of act- 1ng as an obstruction to the fuel and serving as a Vmixing chamber in additiony to'v its function asa vaporizer. V f y This nozzle is formed of ajsingle castin preferably of brass or other suitable materiaA and has a barrel or body yportion 7 and a' cone-shaped mouth 8 through which the flame is directed. The barrel portionis provided near the rearof the'same with a downwardly projecting boss 9 terminatingin a hexagonal or square shaped section 11,v which fis secured upon :or otherwise attachedto a reservoir (not shown) which vcontains, Vthe liquid fuel such as kerosene or other hydrocarbons.

In the nozzle which I have shown in the drawing there Iare four 'longitudinal ribs .Y designated vas'1213, 14and'15, respectively, formed integral with the outerrwall r1 6 of the same Vand the ribs 12 andl 14 are connected the front ofthe rfsaidbarrel portion and 3Jdla-cent1the,Coneshaped `mouth 8,' while'a transverse rib 18 is formed Vimmediately Hbehind the' rib 17. and connects withy ythe chamber 21 rextending through the said "barrel portionjand adaptedV to receive the fuel mixture through the opening 22 at the rear thereof.' The ribs 12 and 14 are each drilled from the rear ,of vthe nozzle to provide the passage-ways `23 and 24 rand theseV passage-ways ,communicatcrwith a passage way'f26 drilled'. through the transverse rib 17. The rear'ends ofthepassage-ways 23 fand 24 are closed by studgbolts 27.*and 28 secured into the same as vshown in the drawing but other solder may be used if desired, and the bottom opening through which the PaSSage-way 26, has .been drilled into the rib 17' is closed by silver soldering or plugged ,as shown at 29. vThe ribs 13 .and 15 are also Fig. 4 is a similar view'taken on the Vline y A35 by'a. transverse -rib 17 which is locatedv in i' provided with drilled passages 31 and 32 and the inner ends of said passages communicate with a drilled passage 33 extending through the rib 18 and the rear end of the passage 31 is plugged or closed by a stud bolt 34 secured into the same. The bottom of the passage 33 is silver soldered as at 36 and the passage 32 communicates at its rear end with a pipe 37 which is threaded into the saine as at 38 and the joint silver sol.- dered as at 39. The rib 19 extending between lthe longitudinal ribs 13 and 14 is provided with a passage 40 which communicates with the longitudinal passages v24 and 31 andthe outer end of this passage, which constitutes the drilled opening, is provided with a plugV 45 for closing` the same.

rlheouter end of the pipel 37 is threaded into the end of the arm 40 onV the member 41 and silver soldered or plugged as at42 and t, this arm is also providediwith a passageway 43, which is drilled into the same, and the outer end of the drilled passage-way closed, as at 44, with silver solder. At the eXtreme frontend ofthe member 41 is the ejector` nozzle 46 through which a needle' 47 is adapted to project. The regulating valve is provided with an operating handle 48 `at the rear end of the member 41 and said handle is attached to a screw 49 which lhas the valve face 51 for fitting into the seat 52 so that by turning the said handle the ilow of fuel fromthe passage 4,3` to tlieoi'ifice 46 may be permitted or interrupted by the valve 51 and the nozzle be kept clean b v the movement of the needle 47 back and forth through the same. The member 41 is also provided with lugs 53 and 54 to which the end wall 56 of a shield 57vis attached by the screws 58 andthis shield has outwardly flared portions 59 at the lower ends of the same and is Yprovided with a hooked member 61 on thev top thereof for supporting a solderingiron. The

lboss 9 is provided with a central passage 62 which communicates at its upper end with the longitudinal passage 23 in the rib 12 and constitutes the passage through which the fuel from the reservoir (not shown) is admitted under pressure to the vaporizing nozzle. The outer wall 16 of the barrel portion 7 of the vaporizing nozzle is provided with openings 63 between the longitudinal ribs c for admitting air to the central chamber 21 vfor mixture with the fuel.

It will thus be seen that when the `fuel is admitted from the reservoir (not shown) through the passage 62 in the boss 9 into the passage 23 in the rib 12, it takes a tortuous and continuous route through the passage -26 in the transverse rib17, the passage 24 in the longitudinal rib 14, through the passage 40 in the cross rib 19, thence through the passage 31 in the longitudinal rib 13, the passage 33 in the transverse rib 18, the longitudinal passage 32 in the rib 15 and thence through the pipe 37 into the passage 43 in the arm 40 of the member 41, where itis conti'olled by the valve 51 in its entrance to the ejector nozzle 46. vImmediately beneath rthe boss 11 the reservoir is provided with a priming pan (not shown) which is used for heating thenozzle when the torch is first used.

It will be readilyseen that the transverse l ribs 17`and 18, extending across the centialV chamber 21 will retard the free flow of 'the mixture through the mouth 8 of the nozzle y and theseribs will form va restriction against which the fuel vwillstrike when it is ejected from the burner nozzle andit will rebound into the chamber 21 and become thoroughly mixed with air so thatit will be completely burned therein. y f I It will be apparent that thenozzle may be readily construct-ed ofa single casting with the passage-ways drilled as explainedV andV the openings caused by the drill on the outer surface of the saine can be V'plugged ,with sil'- ver solder as described and the longitudinal passage-ways plugged with the stud bolts 27 specific number nor do I limit myself to any of the details of construction herein shown which are capable of wide modification and variation without departing from the spirit of the invention. In order that I may reserve all these variations, modifications and mechanical equivalents, I claim vall such IUD structures as may fall within vthe spirit and j scope of the :appended claims: c,
